Sounds like a problem with the Hyper Board.

SOURCE: Dark Blotches

This is probably caused by dust, either on the mirror, lens, or possibly inside the light engine. There is a 5" dia hole on the side of the back of the tv where you can take out one screw and take the door off. this is just big enough for you to put your hand through to clean the mirror and lens. Hope this helps.

Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.

SOURCE: White dots appearing on Samsung TV screen and multipling each day

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

sound like you have a bad dlp chip. this happens to a lot of samsung dlp tvs. some of the mirrors are stuck. they can appear as black dots or white dots and it usually gets worse over time.

I have a 55 inch rear projection mitsubishi tv. it recently has started showing what looks to be white spots when viewed at a distance on a dark screen. when you look at it closely it actually is red green...


It is called Convergence. You have three CRTs. Red, blue, Green. When they are not aligned, you will see the individual colors. See if you can do some alignment in the users menu. Look for Converge or Convergence in the menu. Either under video or setup.

My screen has little dots appearing sometimes red sometimes blues behind the picture i just replaced the lamp bulb as i thought it would cure the problem


the projection tube needs to be adjust for color alignment, each tube (red, green, blue) must be aligned so you there would be no color smear appear on screen. if it is aligned try to set up the color balance, hue etc.

Blue dots on screen. what is it and can it be fixed? a new bulb was recently installed.


Yes,it is repairable.Blue dots on screen is sign of LCD failure at optical block assembly. There are three LCD on the optical assembly RED,GREEN and BLUE. Blue LCD failure causes blue dots on screen. Repair should be done by replacing blue LCD. Note! LCD replacement needs Extra care and precise tools such as oscilloscope and color pattern generator , for the color alignment after replacing LCD. But if you can afford, replacing the optical block is better,

Blue section (corner) and blue dots


This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.

Blue dots in KDF-60WF655


Yes, your optical block ( light engine) is bad. Heat generated by the lamp circuit with its poorly designed ventilation system, cause the LCD panels inside the light engine to fail. They are the size of a postage stamp. There are 3 LCDs, for red, blue, and green. The heat causes them to warp and de-laminate.

Sony has systematically downed played the scope of this issue. It appears however that virtually every LCD projector they make can develop damage in the light engine which is extremely expensive to fix.

I suggest contacting Sony and your state's attorney general's office of consumer complaints asking for action on this.

We have a Phillips plasma tv and the picture pixelates randomly and freezes for about a second and sound breaks also. We have had everything checked and have been unable to find a solution. The latest...


In my openion, Its problem of hardware in your TV and signal processing circuits are involved. It might be problem of Firmware (programe to control the performence over all) Philips can advise you better in this regard.
